A 21-antibody Lanthanide panel (Supplementary Table 3) and FlowSOM clustering identified nine cell types in amounts greater than 0.5% of the total cell population: B cells, CD4+ T cells, CD11b+ macrophages, CD11c+ macrophage/dendritic cells, F4/80+ macrophages, myofibroblasts, endothelial cells, endothelial–mesothelial cells and tumour cells (Fig. 5a). Here, CD4 is linked to neoplasm.
